Runic Firearms

The powers of magic had not come to those who wielded Runic Firearms naturally. Through decades of research, those wielding the powers of these firearms became feared due to their abilities on the battlefield.

Spell crystals

The powers of a runic firearm user come from their crystals, of which hold their spells. By infusing small crystals which serve as bullets with spells, the caster is able to fire magic through their weapon of choice. The user can use their spell slots to create crystals or spend 2 spell slots of the prior level to create a higher level crystal. The crystals reset upon a long rest to be infused with magic once more.

Crystals of alternative classes can be created so long as a scroll of the spell is with the user, but require 5gp to infuse the spell for every level past first.

While they will primarily activate due to magic being injected into them, they can explode once shattered. If they are shattered then a 10ft sphere around the crystal is impacted by the spell cast onto it.

The Big Guns

Beginning at the 3rd level you are able to pick a new firearm type(gaining another choice every 2 levels). Ray firearms(Pistol, Shotgun, Rifle) transform any saving throws into a roll to hit. Explosive firearms(Grenade launcher, RPG, Grenades) cause a 10ft sphere to be affected by the spell(increasing by 5 ft for every spell level), forcing a saving throw(varies on the spell, if it would not otherwise call for a saving throw it is a dex saving throw). 

Bolt Action Rifle

Range 150/600 feet. Fires out a ray of magic, granting advantage to hit and damage rolls so long as no movement is taken.. If the player takes movement on their action they have disadvantage on any attack rolls using this weapon. Can hold 1 spell crystal at a time, takes a bonus action to reload as long as no movement was taken.
